QUICKSTART

Get connected in three steps.

Plug in or pair, give the browser permission, and start dosing.

  1. 1

    Choose your connection

    USB for first-time setup, calibration, and firmware flashing. Bluetooth for ongoing wireless control from any room in the house.

    USB works on Chrome / Edge desktop. Bluetooth works on Chrome desktop and Chrome on Android.
  2. 2

    Grant browser permission

    Your browser will pop up a one-time permission dialog. Pick your LM4 from the list and click Connect. SpectraPure never sees your device — the connection is browser-to-controller only.

    On macOS, you may need to allow the browser to access USB or Bluetooth in System Settings → Privacy & Security.
  3. 3

    Configure and dose

    Set each of the 4 pump channels — OFF, ON, DAILY, DOSE, ONCE, TIMER, or DELAY. Calibrate using a 30 mL beaker. Save WiFi credentials. Done.

    Settings save to the controller itself, so the LM4 keeps running after you close the browser.
